Congress leader Rahul Gandhi and other members of his party on Wednesday walked out of a meeting of the Parliamentary Committee on Defence, alleging that the panel's time was being wasted in discussing armed forces' uniform instead of the crucial issue of national security, sources said. Sources within Congres says that Gandhi was disallowed to speak at the meeting by the panel chairman Jual Oram (BJP) when he sought to raise the issues of Chinese aggression and better equipping the soldiers at the border in Ladakh, they said.
